Problem comes when I want to set up a new Wi-fi connectivity for access points showing in nm-applet list. The set up dialogue box is not opening and the applet keeps on rotating and even shown as connected without asking for password etc.

and then restarted wifi with following
subhamay@subhamay-HP-Pavilion-g6-xubntu:~$ sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
subhamay@subhamay-HP-Pavilion-g6-xubntu:~$ sudo modprobe wl
subhamay@subhamay-HP-Pavilion-g6-xubntu:~$

But my problem is unresolved.
